Hi Henrik
That was an inadvertent mistake and I am sorry. I was looking at another older post ( by title: use a few normal samples as the reference set ). My doubts were almost cleared with that post and I had a small doubt. I could not find "reply" button and i thought "reply to author" button is 'reply' button (which is a mistake again). I appreciate that you spend your valuable time to answer many questions over here. Thanks once again for the answer. --~--~---------~--~----~------------~-------~--~----~ When reporting problems on aroma.affymetrix, make sure 1) to run the latest version of the package, 2) to report the output of sessionInfo() and traceback(), and 3) to post a complete code example.
